DATA ANALYSIS AND DISCUSSION OF THE RESULTS
The purpose of this study is to identify and analyze the relationships that exist between
mathematics anxiety, nurse self-efficacy for mathematics, and medication calculation
performance of acute care nurses. This chapter includes the following sections: (a) Research
Findings, (b) Instrument Reliability and Validity, (c) Data Assessment, (d) Data Analysis, (e)
Results and Analysis for Each Hypothesis, and (f) Summary. Each area is discussed in detail.
The final sample consisted of 84 nurses, licensed vocational nurses (LVNs) and
registered nurses (RNs), from one acute care hospital. Instruments were distributed to
approximately 270 nurses, and 85 were returned completed (30% return rate). One form was
eliminated from analysis due to outliers. The managers distributed the forms, and the nurses
completed them at work or when off duty. A couple of managers encouraged their nurses to
complete the forms, and at least one manager was reluctant to give the forms to the nurses. Most
managers were noncommittal and put the instruments in the employee's communication boxes.
The researcher went to each unit each week and talked with nurses encouraging them to
complete surveys and telling them that if they did not know how to do the math they should
leave the item blank. The hospital census was down from the usual and not as many nurses were
on duty, which made it more difficult to contact as many nurses and encourage participation.
The demographic data items from the instruments are displayed in Table 5. College
algebra grades and college GPA were not reported consistently (over 50% left blank) and were
not tabulated for analysis. The nurses worked in a variety of acute care areas, and a few nurses
Here’s what’s next.
